Data Warehousing

Abstract:Our capabilities of both generating and collecting data have been increasing rapidly in the last several decades. As we all know about large amounts of data that are being dumped into databases , contributing factors include the widespread use of barcodes for most commercial products ,the computerization of many business, scientific and government transactions etc.

Data warehousing

Abstract:Organisations are today suffering from a malaise of data overflow. The developments in the transaction processing technology has given rise to a situation where the amount and rate of data capture is very high, but the processing of this data into information that can be utilised for decision making, is not developing at the same pace. Data warehousing and data mining (both data & text) provide a technology that enables the decision-maker in the corporate sector/govt. to process this huge amount of data in a reasonable amount of time, to extract intelligence/knowledge in a near real time.

Data Mining & Warehousing Architecture

Abstract: Data warehousing is a strategic business and IT initiative in many organizations today. Data warehouses can be developed in two alternative ways -- the data mart and the enterprise wide data warehouse strategies -- and each has advantages and disadvantages. To create a data warehouse, data must be extracted from source systems, transformed, and loaded to an appropriate data store. Depending on the business requirements, either relational or multidimensional database technology can be used for the data stores. To provide a multidimensional view of the data using a relational database, a star schema data model is used. Online analytical processing can be performed on both kinds of database technology. Metadata about the data in the warehouse is important for IT and end users. A variety of data access tools and applications can be used with a data warehouse – SQL queries, management reporting systems, managed query environments, DSS/EIS, enterprise intelligence portals, data mining, and customer relationship management. A data warehouse can be used to support a variety of users – executives, managers, analysts, operational personnel, customers, and suppliers.

Data Warehousing And Data Mining

Abstract: Organizations, in every nook and corner, both large and small, genetic billions of bytes of data related all aspects of their business. But locked up variety of systems, most of this data is extremely complicate to access. Only a very small part of data – captured, processed and stored is available to decision makers.

The challenges of Clustering techniques for High Dimensional Data

Abstract: Clustering analysis divides data into groups (clusters) for the purposes of summarization or improved understanding. For example,cluster analysis has been used to group related documents for browsing, to find genes and proteins that have similar functionality,or as a means of data compression. While clustering has a long history and a large number of clustering techniques have been developed in statistics, pattern recognition, data mining,and other fields, significant challenges still remain.In this paper provide a short introduction to cluster analysis, and then focus on the challenge of clustering high dimensional data . Cluster analysis is a challenging task and there are a number of well-known issues associated with it , e.g., finding clusters in data where there are clusters of different shapes ,sizes and density or where the data has lots of noise and outliers. These issues become more important in the context of high dimensionality data sets. Clustering depends critically on density and distance (similarity) ,but these concepts become increasingly more difficult to define as dimensionality increases.

Dimensional Modeling and E-R Modeling In The Data Warehouse

Abstract: Dimensional Modeling (DM) is a favorite modeling technique in data warehousing. In DM, a model of tables and relations is constituted with the purpose of optimizing decision support query performance in relational databases, relative to a measurement or set of measurements of the outcome(s) of the business process being modeled. In contrast, conventional E-R models are constituted to (a) remove redundancy in the data model, (b) facilitate retrieval of individual records having certain critical identifiers, and (c) therefore, optimize On-line Transaction Processing (OLTP) performance.

Data Warehouses and Data Marts

Abstract: In the beginning, there were only the islands of information: the operational data stores and legacy systems that needed enterprise-wide integration; and the data warehouse: the solution to the problem of integration of diverse and often redundant corporate information assets. Data marts were not a part of the vision. Soon though, it was clear that the vision was too sweeping. It is too difficult, too costly, too impolitic, and requires too long a development period, for many organizations to directly implement a data warehouse.
